Error rates

The error rates stated in this manual assume the following:
The drive is operated in accordance with this manual using DC power as defined in

consumption.
Errors caused by host system failures are excluded from error rate computations.

Assume random data.

Default OEM error recovery settings are applied. This includes full read retries, full write retries and full retry time.

8.3.1

Unrecoverable Errors

An unrecoverable data error is a failure of the drive to recover data from the media. These errors occur due to read or
write problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an
unrecoverable data error is detected, the command will be completed with a Status Code Type (SCT) of 2h Media and
Data Integrity Errors, with code 81h Unrecovered Read Error is reported. Multiple unrecoverable data errors resulting
from the same cause are treated as one error.
8.3.2

Interface errors

An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port
connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or
CRC error.

Endurance management

Customer satisfaction with Solid State Drives can be directly related to the internal algorithms which an SSD uses to
manage the limited number of Program-Erase (PE) cycles that NAND Flash can withstand. These algorithms consist of
Wear Leveling, Garbage Collection, Write Amplification, Deallocation, Data Retention, Lifetime Endurance
Management.
